But now, the FDA has indicated that it has no objection to two stevia products -- Truvia and PureVia -- being used as food additives. Truvia and PureVia are already being sold as tabletop sweeteners.

Truvia was created by Coca-Cola and Cargill. Coca-Cola's first Truvia-sweetened drink is Sprite Green, a reduced-calorie soft drink that will debut in two U.S. cities this month and become more widely available in 2009, according to a Coca-Cola news release that doesn't name the two cities where Sprite Green will debut.

In the news release, Coca-Cola says it plans "many" other Truvia-sweetened beverages in the future, including low-calorie and zero-calorie drinks.

PureVia comes from PepsiCo and Whole Earth Sweetener Company. PepsiCo's first products containing PureVia will be zero-calorie SoBe Lifewater in three flavors (Black and Blue Berry, Fuji Apple Pear, and Yumberry Pomegranate), and a new orange juice drink called Trop50, which will contain 50% less sugar and calories than regular orange juice.

The SoBe drinks are coming "soon" and Trop50 will launch in March, PepsiCo and Whole Earth Sweetener Company state in a joint news release.

The Center for Science in the Public Interest (CSPI) issued a news release that says, "Shame on the Food and Drug Administration" for its decision on rebaudioside A, the stevia extract in Truvia and PureVia. The CSPI calls for further safety tests of rebaudioside A.

"It is far too soon to allow this substance in the diet sodas and juice drinks consumed by millions of people," says CSPI Executive Director Michael F. Jacobson, who calls for the FDA's decision to be reversed.
